// certificate chains of the form:
//
// end-entity (issued by) intermediate (issued by) trusted X509v3 root
//
// where the intermediate is one of X509 v1, v2, v3, or v4, and either does or
// does not have the basic constraints extension. If it has the extension, it
// either does or does not specify that it is a CA.
//
// To test cases where the trust anchor has a different version and/or does or
// does not have the basic constraint extension, there are testcases where the
// intermediate is trusted as an anchor and the verification is repeated.
// (Loading a certificate with trust "CTu,," means that it is a trust anchor
// for SSL. Loading a certificate with trust ",," means that it inherits its
// trust.)
//
// There are also testcases for end-entities issued by a trusted X509v3 root
// where the end-entities similarly cover the range of versions and basic

// Finally, there are testcases for self-signed certificates that, again, cover
